I found this book to be quite fast paced and an easy read. It was definitely an interesting read and is making me think now I've put it down. 

Overall I didn't fall in love with the characters and felt the book was much more focussed on the plot rather than character development. This is obviously fine but in this case it just ended up making me not too fussed about what happened to them.

I found the plot very very interesting and almost wanted more time to explore these different worlds. The idea of these infinite possibilities was kind of mind bending.
